- Key message
- A novel rice acidic pathogenesis-related (PR) class 1 cDNA (OsPR1a) was isolated from jasmonic acid (JA)-treated rice seedling leaf
- SA and abscisic acid blocked JA-induced OsPR1a transcript
- The OsPR1a gene was found to be cut-inducible, whereas the phytohormones JA, salicylic acid (SA), 3-indoleacetic acid, gibberellin, and ethylene (using ethylene generator ethephon, ET) enhanced accumulation of OsPR1a transcript, as well as the protein phosphatase inhibitors cantharidin (CN) and endothall (EN)
- This is the first report on cloning of a rice acidic PR1 gene (OsPR1a), which is regulated by phytohormones, phosphorylation/dephosphorylation event(s), and light
- The OsPR1a cDNA is 830 bp long and contains an open reading frame of 507 nucleotides encoding 168 amino acid residues with a predicted molecular mass of 17,560 and pI of 4
